Red Fort in the context of "Republic Day Parade"

Delhi, officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. Straddling the Yamuna river, but spread chiefly to the west, or beyond its right bank, Delhi shares borders with the state of Uttar Pradesh in the east and with the state of Haryana in the remaining directions. Delhi became a union territory on 1 November 1956 and the NCT in 1995. The NCT covers an area of 1,484 square kilometres (573 sq mi). According to the 2011 census, Delhi's city proper population was over 11 million, while the NCT's population was about 16.8 million.

The topography of the medieval fort Purana Qila on the banks of the river Yamuna matches the literary description of the citadel Indraprastha in the Sanskrit epic Mahabharata; however, excavations in the area have revealed no signs of an ancient built environment.From the early 13th century until the mid-19th century, Delhi was the capital of two major empires, the Delhi Sultanate and the Mughal Empire, which covered large parts of South Asia. All three UNESCO World Heritage Sites in the city, the Qutub Minar, Humayun's Tomb, and the Red Fort, belong to this period. Delhi was the early centre of Sufism and Qawwali music. The names of Nizamuddin Auliya and Amir Khusrau are prominently associated with it. The Khariboli dialect of Delhi was part of a linguistic development that gave rise to the literature of Urdu and later Modern Standard Hindi. Major Urdu poets from Delhi include Mir Taqi Mir and Mirza Ghalib. Delhi was a notable centre of the Indian Rebellion of 1857. In 1911, New Delhi, a southern region within Delhi, became the capital of the British Indian Empire. During the Partition of India in 1947, Delhi was transformed from a Mughal city to a Punjabi one, losing two-thirds of its Muslim residents, in part due to the pressure brought to bear by arriving Hindu and Sikh refugees from western Punjab.After independence in 1947, New Delhi continued as the capital of the Dominion of India, and after 1950 of the Republic of India.

Shah Jahan I (Shahab-ud-Din Muhammad Khurram; 5 January 1592 – 22 January 1666), also called Shah Jahan the Magnificent, was the fifth Mughal Emperor from 1628 until his deposition in 1658. His reign marked the zenith of Mughal architectural and cultural achievements.

The third son of Jahangir (r. 1605–1627), Shah Jahan participated in the military campaigns against the Sisodia Rajputs of Mewar and the rebel Lodi nobles of the Deccan. After Jahangir's death in October 1627, Shah Jahan defeated his youngest brother Shahryar Mirza and crowned himself emperor in the Agra Fort. In addition to Shahryar, Shah Jahan executed most of his rival claimants to the throne. He commissioned many monuments, including the Red Fort, Shah Jahan Mosque and the famous Taj Mahal, where his favorite consort Mumtaz Mahal is entombed. In foreign affairs, Shah Jahan presided over the aggressive campaigns against the Deccan sultanates, the conflicts with the Portuguese, and the wars with the Safavids. He also suppressed several local rebellions and dealt with the devastating Deccan famine of 1630–32.

Independence Day is celebrated annually on 15 August as a public holiday in India commemorating the nation's independence from the United Kingdom on 15 August 1947. On this day the Indian Independence Act 1947 came into effect, transferring legislative sovereignty to the Indian Constituent Assembly. India attained independence following the independence movement noted for largely non-violent resistance and civil disobedience led by Indian National Congress under the leadership of Mahatma Gandhi.

Independence coincided with the partition of India, in which British India was divided into the Dominions of India and Pakistan; the partition was accompanied by violent riots and mass casualties. On 15 August 1947, the first Prime Minister of India, Jawaharlal Nehru raised the Indian national flag above the Lahori Gate of the Red Fort in Delhi. On each subsequent Independence Day, the incumbent Prime Minister customarily raises the flag and gives an address to the nation. The entire event is broadcast by Doordarshan, India's national broadcaster, and usually begins with the shehnai music of Ustad Bismillah Khan. Independence Day is observed throughout India with flag-hoisting ceremonies, parades and cultural events. It is a national holiday in the country.

The Peacock Throne (Hindustani: Mayūrāsana, Sanskrit: मयूरासन, Urdu: تخت طاؤس, Persian: تخت طاووس, Takht-i Tāvūs) was the imperial throne of Hindustan. The throne is named after the dancing peacocks at its rear and was the seat of the Mughal emperors of India from 1635 to 1739. It was commissioned in the early 17th century by Emperor Shah Jahan and was located in the Diwan-i-Khas (Hall of Private Audiences, or Ministers' Room) in the Red Fort of Delhi. The original throne was taken as a war trophy by Nader Shah, Shah of Iran in 1739 after his invasion of India. Its replacement disappeared during or soon after the Indian Rebellion of 1857.

In architecture, pavilion has several meanings;

• It may be a subsidiary building that is either positioned separately or as an attachment to a main building. Often it is associated with pleasure. In palaces and traditional mansions of Asia, there may be pavilions that are either freestanding or connected by covered walkways, as in the Forbidden City (Chinese pavilions), Topkapi Palace in Istanbul, and in Mughal buildings like the Red Fort.
• As part of a large palace, pavilions may be symmetrically placed building blocks that flank (appear to join) a main building block or the outer ends of wings extending from both sides of a central building block, the corps de logis. Such configurations provide an emphatic visual termination to the composition of a large building, akin to bookends.

The word is from French pavillon (Old French paveillon) and it meant a small palace, from Latin papilionem (accusative of papilio). In Late Latin and Old French, it meant both ‘butterfly’ and ‘tent’, because the canvas of a tent resembled a butterfly's spread wings.

The Chandni Chowk (meaning Moonlight Square) is a street market square it is one of the oldest and busiest markets in Old Delhi, India. Located close to the Old Delhi railway station, the Mughal-era Red Fort is located at the eastern fringes of Chandni Chowk. It was built in 1650 by the Mughal Emperor, Shah Jahan, and designed by his daughter, Jahanara. The street spanning the market was historically divided by canals, engineered to reflect moonlight. These canals have since been closed, leaving behind a transformed urban landscape. It remains one of India's largest wholesale markets.

Ustad Bismillah Khan (born Qamaruddin Khan, 21 March 1916 – 21 August 2006), often referred to by the title Ustad, was an Indian musician credited with popularizing the shehnai, a reeded woodwind instrument. His virtuosity made him a leading Hindustani classical music artist, indelibly linking his name with the woodwind instrument. While the shehnai had importance as a folk instrument played primarily by musicians schooled in traditional ceremonies, Khan elevated its status and brought it to the concert stage.

Khan was a devout Muslim but performed at both Hindu and Muslim ceremonies, and was considered a symbol of religious harmony. Owing to his fame, he was selected to perform for the ceremony at Delhi's historic Red Fort as the Indian flag unfurled at the hour of India's independence on 15 August 1947. His music was played (in Raag Kafi) on television every Independence Day. Khan turned down invitations to perform in other countries before 1966, when the Indian government insisted that he play at the Edinburgh International Festival. This gained him a following in the West, and he continued to appear in Europe and North America thereafter.
